A Co-publication between Intercept, Raleigh International and Conaf. This national park in southern Chile is one of the world's true wildernesses, almost unaffected by man's activities. This important book is based on research carried out by scientists from around the world with the support of Raleigh International and the management of the National Parks and reserves of Chile. The research presented here ranges over the earth and life sciences, as well as describing the history of human exploration and indigenous habitation. The unique environments of the park are described in detail and the enormous potential and challenges for further research, education and tourism are discussed.
